Abstract

An investigation was carried out in TRY1 finger millet variety to develop the mutants for desirable traits. Healthy and dry seeds was exposed to ethyl methane sulphonate (EMS) viz., 15%, 0.30%, 0.45%, 0.60% and 0.75%. Seedling parameters and yield contributing characters were analyzed. In laboratory experiment, germination percentage (90%), the maximum root length of 5.71 cm and shoot length of 3.86 cm on 13th day were observed in the treatment of 0.15% of EMS. The seedling length of 9.58 cm for 0.15% EMS treatment which showed the maximum length among all the treatments. In case of vigour index, maximum vigour index of 913.26 was recorded at 0.15% of EMS treatment. The minimum vigour index was observed in 0.75% of EMS treatment. In case of Stress tolerant index, 0.30% of EMS treatment recorded the maximum stress tolerant index of 114.89 than any other EMS treatments. By considering all these results, 0.15% EMS treatment showed the desirable values to the said parameters than any other treatments. In M generation, 0.15% of EMS treated plants showed a early flowering among all other treatments. The maximum plant height, tillers per plant, productive tillers per plant, finger number, finger length, 1000 grain weight and grain yield were observed in 0.15% EMS concentration. Hence, it was observed that 0.15% concentration showed the desirable values and these values were decreased with increasing concentration.
